I got this error after updating library com.google.firebase:firebase-core:16.0.6
to version 16.0.7.
Could not get resource \'https://dl.google.
This also happened to me, I solve the problem by changing gradle/wrapper/gradle-wrapper.properties file in the following way:
distributionUrl=https\://services.gradle.org/distributions/gradle-5.2.1-bin.zip
According to https://docs.gradle.org/current/userguide/gradle_wrapper.html use the -all distribution to enable your IDE to enable code-completion and being able to navigate to the Gradle source code. (as @maxf mentioned)
distributionUrl=https\://services.gradle.org/distributions/gradle-5.2.1-all.zip
